Description

Degassed packed frozen sushi and its manufacturing method

The present invention relates to a frozen sushi suitable for thawing, and more particularly to a frozen sushi suitable for thawing with a microwave oven. In addition, the present invention protects a device which is not preferably heated to 40 ° C. or higher by being heated to 40 ° C. or higher by using Laminate M foil, from the microwave mouth wave of the microwave oven. Degassed frozen sushi with range thawing. Furthermore, the present invention provides a plastic product in which a sushi formed by placing a lazier preferably placed at a high temperature of 40 ° C. or higher on a form is stored in contact with the laminate foil. ¾ box, made of plastic and plastic film ^ ^; in a degassed state, ¾ sushi power is tightly attached to the plastic film of the ¾ bag, and it is packed in one piece. ^^ Frozen sushi suitable for thawing with a range. Background art

For example, sushi such as Tsuruji and other sushi are molded, and on this molded «shaped body, for example, bonito, red sea bream, fish salmon ingredients, vinegar, A white plate boiled in juice made with sugar and salt! Put together with ^ and form into various shapes of ^ ^, wrap the molded sushi in bamboo skins, wrap in plastic film packaging bags, deaerate and wrap this into ETanoichi Λ Or by air blasting, or freezing with nitrogen or carbon dioxide ^ g, etc. Degassed frozen sushi is manufactured by placing the frozen Cheng Kaiji in a plastic film packaging bag and degassing it.

This kind of brine ^ male frozen sushi is degassed in ¾; therefore, ¾; there is no absorption of bacteria and odor of cooling gas in the cocoon chamber. For example, it is superior in terms of hygiene compared to frozen sushi that has been degassed after freezing by sushi freezing by air blast freezing or nitrogen or carbon dioxide freezing. In particular, frozen salmon sushi frozen with Brine can be stored in a frozen state for a long period of 3 months or more, for example, under 18 ° 0¾, and at a storage temperature of 150 ° C. Then, it can be stored for over 6 months.

However, this frozen frozen sushi is thawed and served. In this packaged frozen sushi, there are natural freezing, running water freezing, steam thawing, hot water thawing, and electronic len ^^ freezing. Because it is extremely short and has a high thawing yield, it is suitable for thawing frozen sushi. For example, in the case of the above manager, room temperature thawing requires 5 hours for thawing, but e-len refrigeration can be thawed in 4 minutes. Convenient to meet demand immediately. (JP-A-8-2 1 4 8 05, JP-A-8-3 1 7 4 6-5, JP-A-9-4 7 2 4 2, JP-A 2 0 0 0-2 7 5 5 (See 9 1 Gazette, US Patent No. 5, 8 6 1, 1 84)

Defrosted with a microwave oven: ^, The part with the tool has a different amount of heat generation due to the absorption of microwaves, and the quantity is also different. Since it is heated compared to the part, a part of the ingredients are heated to an unfavorable level as compared to the soup, so that it is in a so-called boiled state, and it is regarded as a problem of the taste and is not practically used.ヽ. Moreover, For example, it is preferred that Tsuruji's register part is Al, for example 15 to 25 ° C, preferably 20 to 25 ° C, but the tool part is lower, for example A force S between 1 and 25 ° C ^^, preferably between 10 and 20 ° C is preferred. By the way, in order to defrost frozen frozen sushi in a microwave oven, it is difficult to perform the intended thawing with a microwave oven because the ingredients of the sushi are heated to a relatively low temperature and the taste of the sushi is impaired. ing. Therefore, in order to solve the problem that the ingredients of Toshiji are heated to a relatively high temperature when thawing frozen salmon sushi with a microwave oven, etc., the taste of the sushi is impaired. Wrap the sushi with the ingredients in a plastic film for wrapping, place the metal foil on the ingredients, and wrap the sushi in a plastic film for wrapping. The sushi is degassed into a plastic film ^^ made of frozen food and sealed, and in this sealed state, the whole is frozen with brine and suitable for frozen storage. Proposed so-called frozen sushi

Place the plastic film for wrapping on the sushi ingredients, place the foil on the sushi ingredients, and then tilt the sushi ingredients together with the plastic film for wrapping frozen In the case of sushi, when it is thawed by electromagnetic wave heating such as a microwave oven, it is not covered with metal foil but exposed to microphone mouth wave irradiation «The part is heated by microphone mouth wave and warmed, but ^ foil is placed The part of the tool that is shielded by the microwave is not heated by the microwave, but remains frozen. Water vapor force S is generated from the portion heated by the decoration and heated, and this generated water vapor is trapped inside the plastic film for wrapping and heated from the microwave oven and from the microwave oven. Even after taking out, the inside of the plastic film for wrapping is steamed and warmed, and the tool can be warmed to 1 o ° c¾g by using as a human skin. In this way, frozen sushi is wrapped in plastic film for wrapping with foil placed over the surface of the utensil so that the utensil is not heated by microwaves ^ ^ It is suitable for thawing with a microwave oven. Wrapped and wrapped in plastic film for wrapping with foil ^^ Frozen sushi was wrapped in plastic film for first wrap so that no thighs would occur from the foil 5¾¾ during microwave irradiation Place the foil on the frozen sushi ingredients, wrap it in a plastic film for the second wrap, and keep it electrically connected to the surroundings. Moreover, when wrapping with the plastic film for the second wrap, it is necessary to place the metal foil on the frozen sushi ingredients without slipping, and the sushi is placed on the plastic film for wrapping. It is necessary to wrap it in a woven cloth. These cocoons in the production of frozen sushi wrapped in plastic film for wrapping are all healthy and require caution, requiring cocoons and making cocoons difficult and problematic. Frozen sushi wrapped in plastic film for wrapping is a problem because it requires a lot of manpower and time to meet customer demand.

An object of the present invention is to solve the problems of frozen sushi wrapped with plastic wrap for wrapping and to prepare a frozen sushi suitable for thawing with a microwave oven.

For example, the present inventor can degas the box with a box for each box and AL for a flexible packaging bag, so that the flexible bag for packaging is pushed by external pressure to the box. Discovered that it can be attached to the outer surface and inner surface of the sushi and the outer surface of the sushi exposed from the box while the internal force is reduced, and when heated in a microwave oven, the calorie heat can be generated by steaming the ingredients.

In the present invention, sushi means sushi, pressed sushi, battera or nigiri sushi. In the present invention, sushi is frozen by placing AL in a plastic box with a laminate foil on the bottom, AL, sushi in an open plastic box, and flexible plastic. Put in a wrapping bag made of 50 to 60 O mmH g, preferably 1550 to 400 mmHg, more preferably 1550 to 35 OmmHg, ie degassing Then, the degassed bag is subjected to brine freezing, air blasting, nitrogen or carbon dioxide, etc. In case of frozen frozen sushi, sushi sushi is made of AL and degassed and flexible plastic packaging bags are manufactured with brine ^ ^. And preferred. Also, in the present invention, the sushi packaged frozen sushi is a sushi in which the ingredients are arranged on a molded body, for example, Tsukasa, Hako sushi and υ¾ι sushi, etc. A single sushi can be packed and frozen, but multiple sushi can be frozen together. When making multiple sushi in a box with AL and sushi with a box in a bag to make aeration-packed frozen sushi, each sushi is made of a flexible plastic film made of a rice cake that does not shield the microphone mouth wave. It is preferable to use tb ^ U with a steam wrapping wrapping with steam or a plastic tt ^ piece, so that the adjacent sushi will not adhere to each other after thawing. The sushi used in the present invention may be a sushi that can be cut off.

In the present invention, the sushi, te, box, and ^^ are made of material that is not shielded, such as a plastic box and plastic ¾ s. The In the present invention, when the sushi is wrapped in a plastic box, the laminated metal foil is placed at the bottom of the box where the sushi ingredients fit, so when the microwave oven is heated, It is shielded by laminating foil, so that the parts of the tool can be prevented from being heated by the microphone mouth wave. In the present invention, the laminate M foil is sufficient if it shields microwaves and does not cause ¾ m between the microwave oven and the foodstuff. In the present invention, a laminated metal foil is a metal foil such as an aluminum foil that is entirely covered with an electrochromic material such as plastic, or an electrical insulation such as a plastic that does not produce a foil. It is covered with the material.

In the present invention, the plastic box that accommodates sushi can be shaped like a commonly used box, and the bottom is large enough to accommodate sushi when the sushi is accommodated. The side and front cross-sectional shapes are formed following the shape of sushi. The plastic box that holds the sushi is formed so that the width of the opening and the width of the plastic are larger than the width of the bottom and the width of the bottom, respectively, so that the sushi can be served easily. I like it. In this way, if the box opening is formed wider than the bottom, sushi delivery A will be easier. Moreover, it is preferable because a space can be formed around the sushi. In the present invention, the plastic formed by plastic phy / rem, which can be ffiffl to the force of heat 13 by the microwave oven, that is, the space formed around the sushi in the ¾E state in the bag for the electronic range, At the time of thawing, there is little change due to the wrinkles inside the bag, which is preferable because it becomes a space between the sushi and the box and between the box and the miscellaneous bag. In the present invention, a flexible plastic film made to a pressure of 50 to 60 O mmHg, preferably 1550 to 40 OmmHg, more preferably 1550 to 35 OmmHg. In a microwave oven package, for example, the gap formed between the box and the sushi and between the box and the bag, that is, the space formed around the sushi is used when the sushi frozen by the microwave oven is heated. By heating the microwave, for example, the water vapor generated from the frozen sushi form flows through the formed space and is heated to heat the body part and the ingredient part that are thawed and low in temperature. Can do.

In the present invention, the space in which the sushi zodiac is formed becomes less effective as the steaming effect becomes smaller, and the smaller the space, the more steaming takes. In the present invention, the size of the space formed around the sushi is less than or equal to the volume of the sushi, and is set to 0.1 to 0.7, preferably 1. 2 to 0.5. The ratio of the sushi in the space around this sushi to the sushi in the sushi pavement set to 1 can be increased as the pressure force in the EE bag is lower. According to the present invention, the volume of the space formed around the sushi in the packaging bag for the flexible microwave oven made of the plastic film, which is made of an internal force, is a plastic film made of an internal force. The volume in the packaging bag for the flexible microwave oven made from the box is removed.

In the present invention, the bottom of the plastic box is the place to remove the sushi ingredients, Laminated ^ S foil is placed. In the present invention, since the laminated straw foil is provided so as to cover the sushi ingredients, when thawing with a microwave oven, it occurs between the ¾m or ^ s foil and the sushi between the foil and the wall surface of the microwave oven. Can avoid ¾m that occurs in In the present invention, the plastic laminate foil is provided so as to cover the tool so that the microphone mouth wave is not irradiated to the tool. In the present invention, the shape and tool are AL to plastic film ^^, degassed and sealed, so that the ^ iW body and tool once trapped will be intruded by outside air and wet bacteria. It is a structure that can avoid as much as possible.

In the present invention, the sushi is thawed by, for example, a microwave oven. The sushi slab molded body is thawed by heat generated by absorption of a microphone mouth wave irradiated by the microwave oven. Since the sushi ingredients are covered with laminated metal foil, the sushi ingredients are thawed exclusively by the heat and steam generated in the sushi shape. Therefore, in the present invention, the thawing of frozen sushi is related to the weight of the frozen sushi. For example, the frozen ¾ bag is thawed in a microwave oven for 2.5 to 5 minutes by micro mouth heat. Then, the frozen molded body is mainly thawed, and then, without opening the bag, for a period of 30 minutes or less, more preferably for a period of 20 minutes or less, for example, in the chamber or water. Leave it in the water after cooking in a room or steam it with steam generated from the mm ^ body to heat the sushi shape and ingredients, and to add the ingredients by adding the cooked rice The frozen sushi is thawed by heating.

In the present invention, the distribution of sushi heated by a microwave oven when thawing box sushi or stick sushi with a microwave oven was measured. The W¾ shape * ¾ portion above the tool is higher than the tool due to its position above the tool, and the upper part is higher in the rice shell part, and the microwave force S It gets higher as it gets closer to the corner to concentrate. For the side of the feature part, it was found that the force s small rule is a higher key than the large area. Tsuruji's Tsuruji heated in a microwave oven is cut into a size suitable for eating, but the shape after thawing is high, and the stickiness between the stand is large Because it is difficult to separate, the shape force S collapse; ^ is less than 10 ° C and less than 30 ° C, preferably more than 15 ° C and less than 25 ° C. «The strength of the« molded body «is reduced by reducing the sticking between each other and making it easier to separate.

In the present invention, after thawing sushi by micro Higuchi heat,

In order to use the heat to cool the cooking equipment, the cocoon is thawed in the miscellaneous sachet without steaming the rice cake, raising the quality of the equipment and lowering the shape. In the present invention, a space is formed around the shape in the packaging bag, and steaming is efficiently performed by freezing water vapor during thawing, so that the shape can be formed in a relatively short time. The temperature can be made easy to cut, and the thawed frozen sushi can be made easy to cut. In the present invention, at the time of thawing, the upper inner surface of the packaging bag and the laminating foil that have been frozen by freezing when frozen are formed into a fortified space, and water vapor enters the formed space, and the sushi shape and The ingredients are steamed and heated with steam.

In the present invention, a plastic box that accommodates sushi is used without a lid so that a laminate foil is placed on the bottom and the box is degassed. The sushi is placed in a box with the utensil down, that is, upside down, so that the utensil rolls onto the laminated metal foil. Thus, when the tool is placed down and Ax is placed in the box, the tool is placed on the laminated metal foil placed on the bottom of the box, and the surface of the tool is covered with the laminated metal foil. It will come to be. »The part of the sushi form contained in the box is placed in the plastic box, facing up, without being covered. Plastic box with sushi placed like this The upper part of the box is opened, and for example, it is put into a bag made of a flexible plastic film such as a W film bonded with a polyethylene film and a nylon film. A plastic box containing sushi with the ingredients placed on the laminating machine foil is placed in a plastic bag ^ ¾ bag, and inside the bag, for example, 5 0 to 60 mm H g Degassing to a pressure in the range of 1 50 to 40 O mmH g, and then inside the packaging bag, the difficulty of wrapping withered by the heels, and the inner surface of ^^ is part of the body of the sushi The sushi can be stably fixed in the box. Laminating aluminum The covering of the tool by laminated foil such as aluminum foil is frozen and fixed by degassing ^ »brine freezing. Therefore, when thawing, the covering power of the tool by the laminating foil will not come off. ,. In the present invention, a laminated metal foil such as a laminated aluminum foil coated with an insulating material is used, so that it can be used on the sushi ingredients for shielding microwaves of sushi ingredients, The flexible plastic film ^ ¾ bag is easily deflated during degassing and sticks to the sushi to fix the position of the sushi in the box, so the sushi position is stable when frozen and thawed in the microwave. And ^ S molded body can not be shifted from the foil.

According to the present invention, a sushi is formed by placing an ingredient on a molded body, and the formed sushi is placed in a box in which a laminate foil is disposed at the bottom with the ingredient A and the ingredient is placed. Place the box at the bottom of the box in contact with the laminated metal foil, put the boxing sushi in a flexible plastic packaging bag, deaerate and seal it, and place the inner surface of the flexible plastic packaging bag. The sushi contained in the box is fixed in the box, and the deaerated packaged sushi is removed from the refrigerated refrigerant to release the sushi bag Because the inside is frozen with sushi, it is possible to produce frozen packaged sushi. It is possible to do almost manually, it becomes easy to automate, and it can be hygienically beta. Of high quality frozen packaging sushi Constant production can be performed. In the present invention, the ingredients are placed on the body to form sushi, and the formed sushi is covered with a laminated metal foil so that the ingredients are covered with the laminated ^ S foil. In a plastic box; τ, the whole box can be degassed in a flexible plastic bag, frozen and used as a freezer. Example

In the embodiment shown in FIG. 3, similar to the embodiment shown in FIGS. 1 and 2, the wrapping ¾T frozen sushi 1 is a plastic wrapping 2 on the outside, and the inside of the plastic ¾ sack 2 Contains a plastic box 4 for storing the sushi 3 and is frozen together with the sushi 3 in a degassed state. In this example, the sushi 3 placed inside the ffjf self-plastic packaging bag 2 is the microwave of the microwave oven shined by the sushi ingredients 7 when laminating the sushi 3 Shielded by 9, In order to prevent the sushi ingredients 7 from being heated by microwaves, the ffjf sushi 3 ingredients 7 are placed on the bottom 8 of the fflt plastic box 4 and laminated on the foil 9! It is arranged with down. In this example, the packaged frozen sushi 1 is integrated with the plastic packaging bag 2, the sushi 3 and the laminate S foil 9 together with the plastic packaging bag 2 in the plastic bag ¾. In this example, the laminated metal foil 9 to be frozen on the frozen sushi 1 is a so-called laminate ^ S foil, in which the entire surface of the recording foil 10 is covered with a plastic film 11.

9 force s is formed. In this example, the bent portions 17 and 18 are formed on the front side and the regular side of the laminate foil 9, and the points shown in FIG. 1 and FIG. There is a difference. The other points are the same as those in Figs.

In this example, ^^ Frozen Sushi 1 is placed with Laminate S foil 9 on the bottom 7 of a plastic box 4, and Sushi 3 is placed on top of it, and Sushi 3 ingredients 7 are on the bottom. Place the sushi 3 in the plastic box 4 and place the plastic box 4 containing the sushi 3 in the flexible plastic packaging bag 2 with AL and vacuum the mouth 19 of the bag. Connect to the suction port of the pump (all not shown), for example, deaerate the plastic packaging bag 2 with a pressure of 16 O mmHg or less, and finish degassing After that, the mouth 11 of the packaging bag is densely squeezed with a heating paper.

Since this example is configured as described above, the packaged frozen sushi 1 can be thawed in a microwave oven with the form 12 facing up. It can also be thawed with i 1 2 down and sushi ingredients 5 up. At the age of thawing with the cooked rice 10 up in the microwave oven, most of the microwaves from above are absorbed by the M ^ form, Spending 0 to power the form prevents it from reaching the sushi ingredients and does not heat the ingredients 7 of sushi 3. Microwave from the micro direction is scattered light, and the thickness force S of sushi 3 ingredients 7 is very small, so the area of the irradiated thickness part is small, and there is a box around it For this reason, sushi ingredient 3 is not heated to a high temperature exceeding 10 ° C.

The embodiment shown in Fig. 4 is based on the fact that the front side of sushi becomes significantly higher than the inside due to the heating of the sushi microwave oven. The longitudinal side of the laminated metal foil 6 is formed to be larger than the longitudinal direction of the bottom of the plastic box 4 so that the side surface part 1 3 of the front side can be covered with the laminated metal foil 6. Lay the bottom edge 15 of the laminating machine foil 9 on the bottom of the plastic box 4 along the side wall 16 of the front side of the plastic box. This is an example in which a bent part 17 of the first foil 9 is formed, and this example is different from the example shown in FIGS. 1 and 2 in this respect. However, the other points are the same as those of the embodiment shown in FIGS. In this example, when sushi 3 is placed in a plastic box, the side part 1 3 on the front side of sushi 3 ingredients 7 placed in tm 4 is laminated foil 9 on the bottom of the plastic box. The microwave which is covered with the bent portion 17 formed by the front side peripheral portion 15 of the laminate recording foil 9 and irradiated to the side portion of the front side of the tool 7 from the direction is knitted. It is shielded by the bent part 17 and can avoid heating the front side of the tool 5 by microwaves in the ^^ direction.

In the embodiment shown in FIG. 5, when the bottom of the plastic box 4 is laid, the side edge 15 of the laminated metal foil 9 is aligned with the side wall of the side of the plastic box 4. This is an example in which a bent portion 17 is formed on the side surface side of the laminated metal foil 9 except for this point, and the other points are the same as those in FIG. In this example, plastic When the sushi 3 is placed in the box 4, the side part 1 4 of the side of the sushi 3 ingredients 7 placed in the t 4 is laid on the bottom 8 of the plastic box 4 and laminated recording foil Microphone mouth wave that is covered by the front side bent part 20 formed by the peripheral edge part 1 8 of the side face 9 and irradiated to the side part 1 4 of the side face part 4 of the sushi 3 ingredients 5 from the direction is bent. It is shielded by part 20 and can avoid heating the side of sushi 3 utensil 7 by microwaves from the ^^ direction.

FIG. 6 and FIG. 7 show an embodiment different from the embodiment shown in FIG. 1 to FIG. In the embodiment shown in FIGS. 6 and 7, box 4 is an inverted kamaboko type and is made of polypropylene. As shown in FIG. 7, the shape of the box 4 is an inverted shape of the cross-sectional shape of the mortar. In this example, the cross-sectional shape of the side face of the sushi where the ingredient 7 is arranged at the bottom of the box 4 is formed in accordance with the breaking resistance of the container. In this example, the plastic box 4 with AL ¾ frozen sushi 1 has seven ribs 20 formed to project inward along the inner wall for the supplementary grade 3 cage of box 4 The sushi can be accommodated through the space 21 between the ribs 20, with the utensil 7 down, the body 12 positioned on it, placed on the ribs 20.

The sushi is cut into pieces, and the space between the ribs 20 between the ribs 20

2 can be accommodated in one. In this example, the boss or sushi is placed in the box 4 on the rib 20 with a notch 22 so that it can be cut into 8 slices. In FIG. 6, the notch lines 2 3 and 2 4 indicate that the sushi is not accommodated, and that the rib 20 in the state and the space 21 between the ribs are shown. Of course, this example can be used as a container for sushi, but with a cut. In this example, the force ^s provided on the inner side of the rib can be provided on the outer side. Industrial use

In the present invention, Laminate ^ M foil is placed at the bottom of a plastic box, and the sushi is placed on top of it with the utensil down and the utensil removed from the laminating foil. The position of the laminate foil and the position of the foil becomes simple and easy, and it can be leaked and manufactured in large quantities and efficiently, making it possible to make cheap boxed sushi.
